CVE-2026-42403

Apache Neethi does not properly detect circular references in policy definitions. When a WS-Policy document contains circular policy references (where Policy A references Policy B which references Policy A), the policy normalization process can enter an infinite loop or cause excessive recursion, leading to a stack overflow or application hang. An attacker can craft malicious policy documents with circular references to cause a Denial of Service condition Users are recommended to upgrade to version 3.2.2, which fixes this issue.

Summary		(es) Apache Neethi no detecta correctamente las referencias circulares en las definiciones de políticas. Cuando un documento WS-Policy contiene referencias circulares de políticas (donde la Política A hace referencia a la Política B que hace referencia a la Política A), el proceso de normalización de políticas puede entrar en un bucle infinito o causar una recursión excesiva, lo que lleva a un desbordamiento de pila o a un bloqueo de la aplicación. Un atacante puede crear documentos de políticas maliciosos con referencias circulares para causar una condición de denegación de servicio. Se recomienda a los usuarios actualizar a la versión 3.2.2, que corrige este problema.
